![]() ![]() There is a lot of discussion concerning ISO in this and other chapters, however it might be helpful knowing where your starting points should be for your ISO settings. For our purposes, let’s just select ISO 400 to ensure that we provide enough sensitivity for all those shadows while allowing the digital camera to use shutter speeds which are fast enough to avoid motion. It’s a balancing act, with all the main goal always being to keep the ISO as low as possible-too low an ISO, and we will get camera shake in your images from the long shutter speed and too much an ISO means we’ll have an unacceptable volume of digital noise. The lower the ISO number, better the quality of our photographs, nevertheless the less light sensitive the camera becomes. Well, in Program mode, you are able to choose which ISO you would like the digital camera to base its exposure on. From Chapter 1, we all know that Auto ISO is simply not a consideration, and we all have already turned that come with off (you probably did turn it off, didn’t you?). As I said, the light is moving from deep shadow to bright sunlight, which means that the camera is trying to balance our three photo factors (ISO, aperture, and shutter speed) to produce a good exposure.
